Sudden burst of spring litters Minnesota roads with potholes

Potholes are multiplying on Minnesota roads, and officials warn it could be bumpy for a while.

One right after another, drivers hit gaping potholes on Interstate 94 in downtown Minneapolis - and one after another, they felt their tires go flat.

The recent spate of damage that led to costly repairs could be a sign of things to come as record-breaking snow combines with a burst of wet spring warmth this week to open up a robust constellation of potholes on freeways, county roads and city streets.
